sim.exportMesh

Exports a mesh to a file

Synopsis

sim.exportMesh(int fileformat, string pathAndFilename, int options, float scalingFactor, 
               list vertices, list indices)

sim.exportMesh(int fileformat, string pathAndFilename, int options, float scalingFactor, 
               float[] vertices, int[] indices)

Arguments

fileformat: the fileformat to export to:
- 0: OBJ format
- 3: TEXT STL format
- 4: BINARY STL format
- 5: COLLADA format
- 6: TEXT PLY format
- 7: BINARY PLY format
pathAndFilename: the location of the file to create.
options: keep at 0
scalingFactor: the scaling factor to apply to the vertices to export
vertices: an array of vertice arrays. See the example below
indices: an array of indice arrays. See the example below

Return values

Example

--lua

-- Exports all shapes in the scene
local allVertices = {}
local allIndices = {}
local shapeIndex = 0
while true do
    local h = sim.getObjects(shapeIndex, sim.object_shape_type)
    if h < 0 then
        break
    end
    shapeIndex = shapeIndex + 1
    local vertices, indices = sim.getShapeMesh(h)
    local m = sim.getObjectMatrix(h)
    for i = 1, #vertices // 3, 1 do
        local v = {vertices[3 * (i - 1) +1], vertices[3 * (i - 1) + 2], vertices[3 * (i - 1) + 3]}
        v = sim.multiplyVector(m, v)
        vertices[3 * (i - 1) + 1] = v[1]
        vertices[3 * (i - 1) + 2] = v[2]
        vertices[3 * (i - 1) + 3] = v[3]
    end
    table.insert(allVertices, vertices)
    table.insert(allIndices, indices)
end

if #allVertices > 0 then
    sim.exportMesh(0, "d:\\example.obj", 0, 1, allVertices, allIndices)
end
